The CDT: Idaho and Montana

When it comes to hiking the CDT through Idaho and Montana, it’s worth noting how incredibly scenic – yet remote - much of the trail can be. In fact, there are numerous disagreements about the exact route the trail follows, especially as you get further north. Wildfires, weather, and land ownership all play their part. The trail also traverses some of North America’s most vast wilderness areas, such as the massive Bob Marshall Wilderness Complex, a multi-million-acre plot in the heart of Montana. In fact, the CDT Coalition even notes the megafauna such as grizzly bears and wolves that thrive throughout a region lined with 1,000-foot-high rock escarpments just off the trail. As such, bear-proof canisters and bear spray are a must for hikers.

Highlights of the trail include Glacier National Park and numerous Gateway Communities along the way. Anaconda, Lincoln, Helena, and the greater Lemhi County all offer welcoming amenities to hikers and the chance to resupply. That said, thru-hikers making their way north to Canada must be mindful of timing, as winter weather can hit many of the mountaintops as early as September. By October and November, most portions of the trail will be covered in snow.

When it comes to completing the trail, you have several options to choose from. The traditional finish is to hike to the Border Monument and finish your life-changing trip off with a 4-mile hike into Canada. That, however, requires extra planning since a passport is needed for both hikers and the vehicle that plans to pick them up. As an alternative, the Chief Mountain Teriminus sits just within the US boundary and eliminates most of those worries. The route also follows lower elevations that tend to be free of snow when the Waterton Route is unpassable. Of course, a road walk is always an option as well, though it's less scenic and exciting than most would prefer.

Of the other need-to-know items, dogs are allowed on most parts of the CDT, but they are prohibited within Glacier National Park. Water is usually abundant here, and waist-deep river crossings are not out of the question at times. Snow, wildfires, and other trail closures are all variables to be aware of if you’re hiking north, and massive changes in elevation can yield summer thunderstorms atop the highest peaks or snow, depending on the time of year. Even so, the Montana and Idaho sections of the CDT yield some of the best views and most remote terrain the trail has to offer, so don’t hesitate to plan a section hike or day hike along any of these segments.
